man Empire, have invented certain new'and' useful Improvements 1nVAlrshlps, of which l' the following is a -full, clear, and exa'ct den'scription The present invention relates to balloons vof alldescriptions but more particularly. to dirigible balloons and consistsin suspending from the balloon auxiliary cars in addition to the maincars.

The main car of a balloon is, as is well known, suspended verticallybeneath the balloon. In the present case itis proposed Vto vprovideauxiliary cars at either side of ent of the main car.

are derlved from these auxiliary cars, for

the main car, which hang approximately t-angentially from the body ofthe balloon Vand which are to a certain extent independ-l Certainadvantages instance, in the case of warfare the space above theballoonmay be watched from the auxiliary cars, while this would beimpossible from the main car owing to the fact that -the balloon itselfwould obscure the view.

If the balloon is to be employed for advertising or for signalingpurposes, the lateral suspension of the auxiliary cars enables thelightto be more directly distributed on to the lower part of the body' of theballoon, so that the signal or advertisement displayed on the same willbe more directly visible from the earth. f

In certain cases the main car might be -omitted altogether and twolateral cars provided, which may be 1rigidly'connected together and asit were saddled on the balloon.

In order to render the present specification easily intelligiblereference -is had to the accompanying diagrams, of which Figure 1illustrates a front view ot a bal? a main carand two auxiliary loonl'havin ig. 2 is a side elevation of the cars, and same.

'Referring first to Figs. 1 and 2,' Fig. 1 represents the body orenvelop of the balloon, to which is attached in the usual manner themain car .2. ,The vauxiliary cars 3 are suspended at eltlier'gsidefofthe main car v byrmeansof suitablewires or ropes 5 and upper pulleys 6,from which vbranch ropes or wires 7 are attached-to different points ofthe envelop netting in the usual manner. Between the wires or ropes 5and the pulleys 6 blocks arearranged, over which the lines -10 run,which extend by means of l1ne.s 51 to the car, so that the height of theauxiliary cars may be varied as regards the mam car by shortening orlengthening the lines 51. The auxiliary cars 3 are advantageously linkedto the main car 2 by means of rigid arms S, so that on being raised theywill also be spread away from the main car, and their lowest position isadvantageously such that a line drawn vertically upward will meet thesides of the envelop at a tangent, as will' be readily understood fromthe drawings.

The auxiliary cars 3 are advantageously employed for carrying the lightprojecting apparatus 4- and the dotted lines 9 show -how the light isprojected on to the lower surface of the envelop more advantageouslyfrompthese points than it could be from the main car. These cars mayhowever bemade sufficiently large to carry persons when this 1snecessary for purposes of observation. For purposes of war theauxiliarycars may be employed to carry explosives which would then be-well out of the way'of the motors in the main car, so that there wouldl e no danger of inadvertent explosions taklng place. i

In some cases the auxiliary cars 3 may be adapted to carry the motor andpropellers, after the manner ofa twin screw vessel, so that the main car2 would be relieved -of the vibrations of these parts and could servefor the recept-ion vof the passengers. In this case also the steering ofthe balloon would be'rendered more eicient, in that it could be effectedby means of the propellers.

When the balloon is employed for advertlsing purposes it may beadvantageous tol provide more than one auxiliary car at each side, forinstance two or three, one behind dei-ed possible while the balloon istravelmg. y

I claim as myinventiom- 1. In a balloon the combination of a' main car,auxiliary cars suspended at each side of the same from the body of theballoon and means for varying the height of the auxiliary cars asregards that of the main carfrom the latter, substantially as de# lscribed.

2. VIn a balloon the combina-tion of a maincar and auxiliary carssuspended from the envelop at each side of the same anda rigid A arm tolink each of the auxiliary cars, to the main car, substantially asdescribed.

. 3. In a balloon the combination of a inain car and auxiliary carssuspended ateach side of the same,'a rigid link to connect the auxiliarycars 'to .the main car, and'means for raising and lowering the auxiharycars from' the. main car, substantially as described. v l

In testimony whereof I aiiix my slgnature Yin' the-presence of l twowitnesses.
